ATTORNEY? Patented June 16, 1936 2,044,472 GLUING MACHINE Joseph Ettl, Plainfield, N. J assignor to Potdevin Machine Company, Brooklyn, N. Y., a corporation of New York Application November 2,1924, SerialNo. 751,171 21 "Claims. (01. 91-50) This invention is directed to an improvement in gluing machines and provides a. machine capable of handling either paper or cardboard, and

among the objects of the invention is the provision in such a machine of an improved arrangement of the feeding rollers which facilitates proper application of the glue to the surface of the material being handled, and a machine which is so constructed and arranged as to make the same readily accessible for purposes of cleaning,

for instance.

A still further object of my invention is the provision of a machine of the general character above referred to in which the stripping fingers by which the paper or cardboard is stripped from the gluing roller as the material passes through the machine are of improved construction.

In the drawings accompanying this application I have shown one embodiment of my invention,

Fig. 1 being a side sectional elevation of the machine;

Fig. 2 a diagrammatic view of the driving mechanism of the various parts of the machine;

Fig. 3 a side elevation of the machine with the transfer roll and the glue applying roll in raised position; and

Fig.- 4 a plan view of the machine.

Referring to the drawings in detail, my improved machine comprises side frames 1 and 2 supporting a feed table 3. The side frame I carries the driving pulley t which is driven through belt 5 for instance from an electric motor (not shown) or other suitable source of power.

The pulley Q is mounted on a stub shaft 6 and this shaft carries a gear 1 meshing with gear 8 on stub shaft 3 mounted in the frame of the machine, this shaft 9 carrying a gear I0 meshing with intermediate gear II which gear meshes with gear l2 on the shaft i3 of the conveyor roller M for the belt discharging conveyor or delivery belt l5.

The gear l2 meshes with gear l6 which through gear l'l drives feed roller l8 which as will be seen from Fig. 4, for instance, extends transversely of themachine.

Shaft l3 of the conveyor roller l t at the opposite side of the machine from the gear l2 carries a gear l9 which through intermediate gear 20 drives a gear 2! on the shaft of the feed roller 22 which roller lies parallel to the feed roller It. The gear train just described for the feed rollers l8 and 22 is such that the roller i8 runs faster than the roller 22.

The feed rollers l8 and 22 are mounted at one end in a vertically adjustable block 23, this vertically adjustable bearing block also mounting the gear l6. On the underside of the bearing block 23 is a support 24 provided with spring 25. The lower end of the support 24 contacts a cam 26 5 on a shaft 21 extending transversely of the machine. At the opposite side of the machine this shaft 21 carries a cam 28'engaging a support 29, provided with a spring 30, for hearing block 3| for the gear 20 and for the ends of the feed 10 rollers l8 and 22, this arrangement being similar to the construction employed at the opposite side of the machine as shown in Fig. 1 and as above described.

At the same side of the machine as cam 28 15 the shaft 21 carries worm gear,32 in mesh with adjusting worm 33, the latter rotatable by calibrated knob 34, rotation of this worm 33 as will now be appreciated effecting vertical adjustment of the bearing blocks 23 and 3| for the feed roll- 20 ers I8 and 2,2 and the gears l6 and 20. The adjustment thus provided permits of the adjustment of the feed rollers l8 and 22 with respect to the gluing roller 35 to regulate the pressure between the feed rollers and the gluing roller and 25 also to accommodate the machine not only to paper of different thickness but to cardboard for example.

36 designates a presser roller mounted adjacent the feed roller 22 and adjacent the lower 30 end of feed table 3, this presser roller 36 being adjustably mounted in its support 31, adjustment toward and away from the feed roller 22 being effected by knob 38.

39 designates a glue pot and 40 a glue roller rotatable therein and adapted to apply glue to the surfaceof roller 4|, the amount. of glue carried on the face of this roller 4! being controlled. by doctor roller 42. The transfer roller M trans- 40 fers glue to the gluing roller 35 with which it is in contact.

The gear I9 on the shaft of the conveyor roller It meshes with a gear 43 on shaft 44 which also carries a sprocket 45 for chain 36 which passes 5 around sprocket t! on the shaft 48 of the glue roller MI and about sprocket 49 on the shaft 50 of the transfer roller M.

The shaft 50 of the transfer roller carries gear 5! meshing with gear 52 on the shaft of the 50 doctor roller 42. The shaft Sll of the transfer roller at the opposite side of the machine from the sprocket chain 46 and on the opposite side of the machine from the gear 50, for instance,

carries a. drive gear .53 meshing with intermedit machine, and these frames pivot about the center of the transfer roller 4|. These frames also carry the presser roller 36. The pinion 54 is also carried in one of these side frames.

Each side frame carries an arm 57 pivoted thereon at 58, these arms being limited in their movement by a part of the frames 56.

Secured to the outer end of each of these arms 5'! is a chain 59,, the other end of these chains being secured to a member 60, these latter members being carried on a rod 6i extending across the machine. 62 meshing with worm 63 on shaft 64 adapted to be rotated by hand wheel 65. The inner end of each of the arms 51 is provided with a latch 66 cooperating with keeper 61 formed in the side frames l and 2 of the machine.

When the machine is in operation the parts are in the position shown in Fig. 1 and under these conditions the latch 66 will be in engagement with the keeper 6! to hold the frames 56 latched in down or closed position. When it is desired to raise thegluing roller 35 the hand wheel is turned and the first movement of this hand wheel will rotate the latching arms 51 on pivot 58 to unlatch the frames 56, continued rotation of the hand wheel raising the gluing roller 35 and associated mechanism comprising the gear 55, pinion 54 and presser roller 36 to the position shown in Fig. 3. When the parts are again lowered to down or closed position the latching mechanism will automatically move into latching position.

Extending transversely of the machine and just behind the gluing roller 35 is a shaft or rod 68 carrying a plurality of stripping fingers 69. These stripping fingers are provided with an open bearing for receiving the rod 68, the tail of each finger designated 10 functions as a counterweight to hold the finger proper against the surface of the gluing roller 35 and to further insure maintenance of the stripping fingers in proper relation to the gluing roller 35 each finger is provided with a spring H engaging the underside of the glue pot 39. The function of the stripping fingers is to strip the paper or cardboard as it passes beneath,the gluing roller 35 to direct the same upon the discharge conveyor I5 and by providing the type of stripping finger above described it will be seen that when the parts are raised to the position shown in Fig. 3

not only is the gluing roller 35 accessible for cleaning purposes, for instance, but the stripping fingers may be simply picked off the rod 68 for cleaning purposes or any other purpose desired.

It will be appreciated also that the stripping fingers may be adjusted relatively to each other or their number varied, as desired, with ease due to the simple mounting of these fingers on their supporting rod or shaft.

As above mentioned the feed rollers l8 and or cardboard, as the case may be, in proper contact with the gluing roller 35 initially, the fast speed roller l8 effecting a clean discharge of This rod 6| carries a worm gear.

the material being treated out of contact with the gluing roller 35.
